Marginalized Beam Search Algorithms for Hierarchical HMMs

1 code implementation19 May 2023 Xuechun Xu, Joakim Jaldén

Inferring a state sequence from a sequence of measurements is a fundamental problem in bioinformatics and natural language processing.

Convex Quantization Preserves Logconcavity

no code implementations11 Jun 2022 Pol del Aguila Pla, Aleix Boquet-Pujadas, Joakim Jaldén

A logconcave likelihood is as important to proper statistical inference as a convex cost function is important to variational optimization.

A matrix-inverse-free implementation of the MU-MIMO WMMSE beamforming algorithm

no code implementations18 May 2022 Lissy Pellaco, Joakim Jaldén

From a theoretical viewpoint, we establish its convergence to a stationary point of the WSR maximization problem.

Inertial Navigation Using an Inertial Sensor Array

1 code implementation28 Jan 2022 Håkan Carlsson, Isaac Skog, Gustaf Hendeby, Joakim Jaldén

We present a comprehensive framework for fusing measurements from multiple and generally placed accelerometers and gyroscopes to perform inertial navigation.

Reinforcement Learning for Efficient and Tuning-Free Link Adaptation

no code implementations16 Oct 2020 Vidit Saxena, Hugo Tullberg, Joakim Jaldén

In this context, we propose a latent learning model for link adaptation that exploits the correlation between data transmission parameters.

Deep unfolding of the weighted MMSE beamforming algorithm

1 code implementation15 Jun 2020 Lissy Pellaco, Mats Bengtsson, Joakim Jaldén

Motivated by the recent success of deep unfolding in the trade-off between complexity and performance, we propose the novel application of deep unfolding to the WMMSE algorithm for a MISO downlink channel.

Thompson Sampling for Linearly Constrained Bandits

1 code implementation20 Apr 2020 Vidit Saxena, Joseph E. Gonzalez, Joakim Jaldén

We address multi-armed bandits (MAB) where the objective is to maximize the cumulative reward under a probabilistic linear constraint.

Constrained Thompson Sampling for Wireless Link Optimization

no code implementations28 Feb 2019 Vidit Saxena, Joseph E. Gonzalez, Ion Stoica, Hugo Tullberg, Joakim Jaldén

We model rate selection as a stochastic multi-armed bandit (MAB) problem, where a finite set of transmission rates are modeled as independent bandit arms.

SpotNet - Learned iterations for cell detection in image-based immunoassays

1 code implementation15 Oct 2018 Pol del Aguila Pla, Vidit Saxena, Joakim Jaldén

Accurate cell detection and counting in the image-based ELISpot and FluoroSpot immunoassays is a challenging task.
